"Giving or receiving oral sex is perfectly safe as long as there is no risk of you getting a sexually-transmitted disease, as your baby can get infected if you contract one," explains Draion Burch, D.O., OB/GYN at Magee-Womens Hospital of The University of Pittsburgh Medical Center.

However, even if contracting an STD is completely out of the question, there is one major precaution you'll want to take. "While this may sound crazy, take care that your partner doesn't blow air into your vagina when you're receiving oral sex," explains Dr. Gottfried. "Theoretically, blowing air into the vagina could block a blood vessel (air embolism), which is dangerous for you and your baby."

You can keep worries at bay by asking that your partner avoid placing his tongue inside the vagina and instead stick to kissing and licking the clitoris and labia (lips around the vagina).

Ultimately, experts encourage women to enjoy oral sex while pregnant. In fact, according to Dr. Gottfried, "for many women who feel uncomfortable due to back pain or swelling, it may be preferred over intercourse."
